Grape phylloxera (Daktulosphaira vitifoliae Fitch) is a major pest of cultivated grapevines (Vitis spp.), occurring in virtually all viticultural regions around the world. Different grape phylloxera strains can be found at varying levels on leaves and roots on both own-rooted plants and in plants grafted onto partially resistant rootstocks. Considering its relevance for the adequate management of the pest in infested vineyards, the analysis of its genetic diversity has received considerable attention from the scientific community in the last decades. Here, we review 25 years of DNA-based molecular markers applied to the analysis of the genetic structure and the reproductive mode of grape phylloxera in its native range and in different introduced regions. The use given to RAPD, AFLP, mtDNA sequencing and microsatellite (SSR) genetic markers for the analysis of grape phylloxera diversity is discussed, and an overview of the main findings obtained after their application to different populations collected in diverse regions all around the world is shown. Lastly, we explore how recent advancements in molecular biology and in modern high throughput genotyping technologies may be applied to better understand grape phylloxera natural diversity at a molecular level.

Asexual Populations

The genetic structure of European grape phylloxera populations, Daktulosphaira vitifoliae (Homoptera: Phylloxeridae), was analyzed using 6 polymorphic microsatellite markers. Genetic diversity data of 6 populations originating from northern and southern European viticultural regions was assessed for geographic differences, and the structure of 2 additional populations was examined in more detail, focusing on specific host plant and habitat charac ter istics. To test for "signatures" of clonal reproduction, different population genetic measures were applied to the data obtained from these populations. A total of 195 multilocus genotypes were detected in 360 individuals tested. Significant deviations from Hardy–Weinberg equilibrium, negative FISvalues (from –0.148 to –0.658 per population), and the presence of multicopy genotypes revealed that the current major reproductive mode at each of the locations tested was asexual. The high genotypic diversity detected within and among populations, however, together with the occurrence of unique D. vitifoliae genotypes, indicates sexual recombination events took place, probably prior to the multiple introductions into Europe. The absence of overlapping genotypes between the sampling sites suggests low migration rates among the populations studied and implies that the main mode of insect dispersal is through infested plant material carried by human agency. The specific features of European D. vitifoliae habitats are illustrated to discuss the role of habitat and life cycle in the genetic structure of this globally important pest aphid species.Key words: Daktulosphaira vitifoliae, microsatellites, genetic structure, asexual reproduction, parthenogenesis.
